Benefits of technology

The patent text describes a battery module that uses a special material to absorb heat and reduce the transfer of heat between battery cells. This helps to prevent damage or failure events caused by heat.

Problems solved by technology

In the battery module, if a spaced interval (e.g., spacing) between the battery cells is increased so as to accommodate (e.g., reduce) a risk or occurrence of swelling of the battery cells (which may be caused while the battery module is charged and discharged), the heat-insulating performance of the battery cells may be deteriorated, or the size of the battery module may excessively increase.

Abstract

A battery module includes a phase change material in an insulation sheet to absorb heat and reduce thermal conductivity, thereby preventing or reducing heat transfer between battery cells, and delaying, preventing, or reducing an event that may be caused by the heat. As an example, the battery module includes a plurality of battery cells and a plurality of insulation sheets interposed between the plurality of battery cells, where each of the insulation sheets includes a heat-insulating sheet having a first surface and second surface, a plurality of through-holes defined in the heat-insulating sheet and passing between the first surface and the second surface opposite the first surface, and a phase change material filled in the plurality of through-holes.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2020-0044756 filed in the Korean Intellectual Property Office on Apr. 13, 2020, the entire content of which is incorporated herein by reference.BACKGROUND1. Field[0002]One or more aspects of embodiments of the present disclosure relate to a battery module.2. Description of the Related Art[0003]Generally, an electronic device (such as a laptop computer, a mini laptop computer, a netbook, a mobile computer, an ultra-mobile personal computer (UMPC), and / or a portable multimedia player (PMP)) uses a battery pack, in which a plurality of battery cells are connected to each other in series and / or parallel, as a portable power source.[0004]In recent years, in order to prevent or reduce environmental contamination, interest in electric vehicles and electric hybrid vehicles has increased, and a battery module in such vehicles may include a plurality of battery c...
